Question

Why does Curley return to the bunkhouse as the men get ready to go for supper?

Answer 1

Answer:

He is looking for his wife.

Explanation:

The men tell him they have not seen her and he begins asking about Slim instead, eventually leaving the bunkhouse to look for him.

He is suspicious that something might be going on between Slim and his wife and he does not trust her, since she tends to flirt with the other workers. He is insecure.
